Demountable rim



CARL A. HARDY, OF BERLIN HEIGHTS, OHIO.

DEll/IOUNTABLE RIT/I.

Application led February l2, 1920.

fo all whom 'it may concern.'

Be it known that CARL A. HARDY, a citi Zen ofthe United States, residing at Berlin Heights, in the county of Erie and State of Ohio, has invented new and useful Improvements in Demountable Rims, of which the following is a specification.

The object of the invention is to provide a dcinountable rim embodying two telescopically connected sections each one of which carries one of the clincher flanges by means of which the tire is held on the rim. To this end the improved rim comprises one continuous section and one split section, l5 the latter beingl readily attachable to the continuous section and positively held in connection therewith when the rim is placed on the telly of a Wheel.

A further object of the invention is to provide a device of the character mentioned, which is simple in construction, durable and effective in operation and inexpensive to manufacture.

To the exact construction in which it is shown and described, the. invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest in so far as such changes or alterations are compatible in spirit with the annexed claim.

In the accompanying drawings:

Fig. l is a view in side elevation of' a vehicle wheel with which the improved rim is used Fig. 2 is a section on the line 2 2 of Fig. l

F 3 is a section on the line 3-3 of Fig. l

Fig. l is a detail perspective view of one end of the split rim section Referring to the drawings, there is shown a vehicle wheel having the telly l. and a 'folly riin 2, the latter at one edge having a rim flange Il designed to preclude the movement 5 of the clincher riin laterally to one side when the clincher rim is mounted on the telly rini as it is in practice. The usual rim lugs 4;

secured in place by bolts serve to retain the rim against lateral displacement on that 5o side of the wheel opposite the flange 3. All of this construction so far described is the ordinary well known construction. The invention resides in the particular form of' demountable rim and this particular form comprises the continuous ring section 6 formed -at one edge with the clincher Serial No. 353,969.

flange 7. Cooperating` with this section 6 there is a split ring section 8 formed at one edge with a clincher flange 9. The ring section 8 adjacent clincher flange 9 is `formed with a shoulder l0 and against this shoulder that edge of the ring 6 opposite the flange 7 abuts when the two sections are assembled. ln attaching the two sections together, the split section 8 is telescoped within the continuous section 6 and this section 8 at its ends is formed with the flange portions 1l on the edge opposite the clincher flange 9. These flange portions ll, however, are oi very short length, extending only along a very short portion of the section 7 and from the split ends thereof. rlhere is also formed with the section 9 at a point diametrically opposite the flange portions ll a third flange portion l2 which is substantially of a length equal to the combined length of the two flange portions ll. These flange portions ll and l2 engage the outer edge of the ring section 6 when the two sections are attached together and the inner end of the section 6 abuts the shoulder l0.

ln attaching a tire, such as the tire ll to the improved rim, it is placed rst on the section 6 with its clincher bead engaging the clinchcr flange 7. 'ihe split ring section 8 is then attached, being inserted in the ring section 6, that portion of the section S containing the flange l2 being first inserted so that this flange may hook around the outer edge of the ring 6. The ring section 8 is then compressed to bring the ends into abutting relation when the flange portions ll may be inserted through the ring to hook around the outer edge of the ring 6 underneath the clincher Harige 7, when the ring 8 expands, the two ends separating. The rim is then ready to be placed on the wheel. and it is preferable to so place it that the section 8 is caused to abut the flange 3 of the 'telly rim. The clamping lugs el' may then be placed in position and engaging the ring 6 serve to hold the riin as a whole on the wheel. @t course, when the rimv is placed over the telly rim 2, the inner section 8 cannot be compressed and this being prevent-ed the shoulder l0 and flanges 11 and 12 serve to hold this inner ring positively connected to the outer ring 6.

rlhe invention having been described, what is claimed as new and useful is:

A clincher rim comprising a pair or telescopieally connected sections each of which 1s provided With a ehnoher flange, the outer of said sections being in the form of a continuous ring, the inner oli said sections being v in the 'form of a split ring and formed With a shoulder against which that edge of the continuous section opposite the clinoher flange may abut, theinner of said sections being formed adjacent its ends and opposite the olinoher llange With short langes which engage the outer section, the said inner section being further formed with a short flange diametrically opposite the lirst said flanges, the inner section being compressible to permit its insertion through the outer seetion whereby the shoulder and the aforesaid short flanges may effect a positive interlock between the two sections.
